By means of this embodiment a household system may be provided with improved properties with regard to a determining routine, in particular for determining a storage characteristic variable. In particular, in this case an advantageously simple rapid and/or accurate determination of the storage characteristic variable may be achieved. Moreover, the determining routine may be advantageously simplified, in particular, since complex object recognition algorithms may be dispensed with, whereby advantageously mistaken identification may be avoided when detecting the consumer product. Moreover, an advantageously user-friendly household system may be provided, in particular since the cooperation of a user may be dispensed with.

Preferably, the consumer product characteristic variable comprises an image characteristic variable and preferably an illustration of the consumer product, whereby, in particular, an advantageously simple detection of the consumer product and/or an advantageously simple determination of the storage characteristic variable may be achieved.

If the storage characteristic variable is at least correlated to a storage location of the consumer product, in particular an advantageous verification and/or monitoring of a storage location of the consumer product, which is in particular correct and/or advantageous, may be achieved.

The detection unit could be arranged outside the item of household furniture and/or household appliance, for example in the form of a web camera and/or a portable detection unit and/or on an outer face of the item of household furniture and/or household appliance and, in particular, may be intended to detect a surrounding area of the item of household furniture and/or household appliance and/or for an interaction with a user. Advantageously, however, it is proposed that the detection unit is intended at least to detect an interior, in particular of a useable space of the item of household furniture and/or the household appliance in which, in particular, the consumer product is arranged in at least one operating state. In particular, the detection unit in this case is also intended to detect a door inner face of the item of household furniture and/or household appliance. Preferably the detection unit in this case is integrated in the item of household furniture and/or household appliance and preferably arranged at least largely inside the item of household furniture and/or household appliance. As a result, in particular an advantageously simple detection may be achieved of a consumer product arranged within the item of household furniture and/or household appliance, wherein advantageously the cooperation of a user may be dispensed with.

In one embodiment of the invention, it is proposed that the detection unit has at least two, preferably at least three, and particularly preferably at least four detection elements, preferably arranged in different corner regions of the item of household furniture and/or household appliance. The detection elements in this case could be detection elements of a different type. Preferably the detection elements, however, are configured to be at least substantially of identical construction.

Preferably, the objects which are at least substantially of identical construction, however, are identical to one another apart from production tolerances and/or within the context of the possibilities of production technology and/or within the context of standardized tolerances. As a result, in particular, a detection of the consumer product may be improved, wherein advantageously at least partially concealed consumer products may also be detected.

The database may be linked, for example, to the Internet and, in particular, may be part of a server network and/or cloud network. In a preferred embodiment of the invention, however, it is proposed that the database is a local database. Advantageously, the database in this case is integrated in the item of household furniture and/or household appliance. Additionally, the database may be linked, for example, to an in particular locally limited home network and/or Intranet and/or form part of a home network and/or the Intranet. As a result, advantageously the storage characteristic variable may be determined irrespective of an Internet connection.

Alternatively or additionally, it is proposed that the database is a cloud database, whereby in particular an advantageously networked database may be provided.

Moreover, it is proposed that the in particular predefined database is a region-specific, in particular country-specific database. In particular, in this case the database is intended, in particular depending on a place of use of the item of household furniture and/or household appliance and/or household system, to store at least partially different region-dependent predefined consumer product characteristic variables and/or predefined consumer product characteristic variables of region-specific consumer products. In particular, the computer unit may be intended to recall consumer product characteristic variables which differ from the in particular different region-dependent predefined consumer product characteristic variables, in particular from the Internet database and advantageously to store said consumer product characteristic variables in the database and/or integrate said consumer product characteristic variables in the database. As a result, a particularly advantageous adaptation of the item of household furniture and/or household appliance may be achieved. Additionally advantageously, consumer product characteristic variables which are not required and/or rarely required may be separated out, whereby advantageously resources may be saved.

In a preferred embodiment of the invention, it is proposed that, when determining the storage characteristic variable and in particular when adjusting the consumer product characteristic variable with the predefined consumer product characteristic variables, the computer unit is intended to consider at least one status information of the consumer product. In particular, the computer unit is intended to use the status information when determining the storage characteristic variable, in particular when adjusting the consumer product characteristic variable to the predefined consumer product characteristic variables. Advantageously, the status information in this case is stored in the, in particular, predefined database. “Status information” is intended to be understood, in particular, as information correlated to a status of the consumer product, such as for example “packaged”, “whole”, “halved” “cut” “diced” and/or “in slices” and, in particular, information characterizing the consumer product, in particular at least approximately and advantageously unambiguously. As a result, in particular, the storage characteristic variable may be advantageously determined in a simple manner.

Moreover, the computer unit is intended to compare the storage characteristic variable with a setpoint storage characteristic variable and to generate at least one advantageously predefined instruction message when the storage characteristic variable differs from the setpoint storage characteristic variable, advantageously by recalling the instruction message from a further database. Preferably, the further database is at least partially identical to the database. Particularly preferably, the output unit is intended to output the instruction message. Advantageously, to this end the output unit comprises at least one output element which is configured as a display. Alternatively or additionally, the output unit may have an output element which is configured as a communication element which, for example, may be intended to transmit the instruction message to an advantageously mobile electronic appliance, such as for example a laptop, a tablet, a smartphone, a smartwatch and/or a similar electronic appliance. A “setpoint storage characteristic variable” is to be understood, in particular, as a characteristic variable which is advantageously predefined and particularly preferably stored in the, in particular, predefined database and which is correlated, in particular, to a setpoint storage, in particular a setpoint storage condition, a setpoint shelf life, a setpoint storage orientation, for example upright and/or horizontal, and/or advantageously a setpoint storage location of the consumer product which is arranged and/or can be arranged, in particular, inside the item of household furniture and/or household appliance.

Advantageously, the computer unit may provide information at least using the setpoint storage characteristic variable about a setpoint storage condition, a setpoint shelf life, a setpoint storage orientation and/or determine a setpoint storage location of the consumer product and/or setpoint storage condition, the setpoint shelf life, the setpoint storage orientation and/or the setpoint storage location of the consumer product. As a result, in particular, an advantageous instruction function may be implemented. Additionally, in particular, an advantageously intelligent and/or user-friendly household system may be provided.

If the instruction message in at least one operating state is a storage recommendation of the consumer product outside the item of household furniture and/or household appliance, in particular a user may be informed about incorrect storage of the consumer product inside the item of household furniture and/or household appliance.

If the instruction message in at least one further operating state is a storage recommendation of the consumer product in a defined partial region of the item of household furniture and/or household appliance which is different from the current partial region, such as for example an upper region of the item of household furniture and/or household appliance, a lower region of the item of household furniture and/or household appliance, a vegetable compartment of the item of household furniture and/or household appliance, a refrigerating chamber of the item of household furniture and/or household appliance and/or a freezer compartment of the household appliance, in particular a user may be informed about a disadvantageous storage of the consumer product inside the item of household furniture and/or household appliance.

In a further embodiment of the invention, it is proposed that the household system has an output unit, in particular the aforementioned output unit, which is intended to output the instruction message, wherein the instruction message is an image of an object which is correlated to the consumer product, advantageously in an illustration of an interior of the item of household furniture and/or household appliance and/or in front of an exemplary background. As a result, in particular, an advantageously intuitive instruction message may be generated.

Moreover, a method for operating a household system is proposed, wherein the household system comprises at least one predefined database which is intended at least to store predefined consumer product characteristic variables of, in particular, predefined consumer products of different types, wherein, in particular, by means of a detection unit at least one, in particular, predefined consumer product which is arranged and/or can be arranged within at least one item of household furniture and/or household appliance, in particular a household refrigeration appliance, is detected, in particular by means of the detection unit, a consumer product characteristic variable correlated to the consumer product is provided and, for determining a storage characteristic variable, in particular by means of a computer unit, the consumer product characteristic variable is adjusted, in particular compared, with the predefined consumer product variables. As a result, in particular, a determining routine, in particular for determining a storage characteristic variable, may be improved. In particular, in this case an advantageously simple, rapid and/or accurate determination of the storage characteristic variable may be achieved. Moreover, the determining routine may be advantageously simplified, in particular since complex object recognition algorithms may be dispensed with, whereby advantageously mistaken identification may be avoided when detecting the consumer product. Moreover, an advantageously user-friendly household system may be provided, in particular, since cooperation of a user may be dispensed with.

The household system and the method for operating the household system in this case are not intended to be limited to the above-described application and embodiment. In particular, the household system and the method for operating the household system for fulfilling a mode of operation described herein could have a number of individual elements, components and units which differ from the number cited herein.

Additionally, the first detection element 30 is intended to detect a position and/or location of at least one of the consumer products 16, 17, 18 and advantageously at least largely the consumer products 16, 17, 18. Alternatively, however, a first detection element could also be configured as a laser scanner and/or CCD sensor.

A second detection element 32 of the detection elements 30, 32 is configured as an optical sensor. The second detection element 32 is configured as an active sensor. The second detection element 32 in the present case is configured as a camera. The second detection element 32 is integrated in the household appliance 12, in particular the housing of the household appliance 12.

The detection unit 14 is intended to provide all detection signals of the detection elements 30, 32 which are correlated to the storage characteristic variable to the computer unit. In this case, the detection unit 14 is intended at least to combine and/or group together all detection signals of the detection elements 30, 32 which are correlated to the consumer product characteristic variable and to provide said detection signals as consumer product characteristic variables to the computer unit 26.

Moreover, the household system 10 comprises a predefined database 20. The database 20 comprises a storage unit. The database 20 is configured as a local database. The database 20 in the present case is integrated in the household appliance 12, in particular the housing of the household appliance 12. The database 20 is connected so as to communicate with the computer unit 26. The database 20 is configured as an image database. Additionally, the database 20 is configured as a region-specific database. The database 20 is also configured to be expandable and may, in particular, if required be expanded, updated and/or adapted by means of the network unit 54. FIG. 2 shows by way of example the database contents of the database 20.

The database 20 is intended to store predefined consumer product characteristic variables 22 of consumer products of different types. In the present case, the database 20 is intended to store a plurality of different predefined consumer product characteristic variables 22, in particular consistently and permanently.

The predefined consumer product characteristic variables 22 in this case are configured as symbols, pictograms and/or illustrations of predefined consumer products. The predefined consumer product characteristic variables 22 are already applied in the present case in a set-up process and/or initializing process of the database 20 and, in particular, stored in the database 20. Additionally, depending on a location of the use of the household appliance 12, such as for example Europe or China, in the present case the database 20 is intended to store at least partially differently predefined consumer product characteristic variables 22 of region-specific consumer products.

Moreover, the database 20 is intended, for each of the predefined consumer product characteristic variables 22, to store status information 34 which is correlated to the predefined consumer product characteristic variable 22. The status information 34 may in the present case correspond to the states “packaged”, “whole”, “halved”, “cut”, “diced” and/or “in slices”. The different states are symbolized in FIG. 2 by way of example by numbers.

Moreover, the database 20 is intended for each of the predefined consumer product characteristic variables 22 to store an in particular predefined setpoint storage characteristic variable 36 which is correlated to the predefined consumer product characteristic variable 22. The setpoint storage characteristic variable 36 corresponds in the present case to a setpoint storage location of a corresponding consumer product. Alternatively, however, a predefined database could also be linked to the Internet and, in particular, be part of a server network and/or a cloud network. Additionally, it is conceivable to dispense with a region-specific embodiment of a database. Moreover, it is conceivable to store status information in a further database, for example a further local database and/or an Internet database. It is also conceivable to dispense with additional status information entirely. Moreover, it is conceivable to store a setpoint storage characteristic variable in a further database, for example a further local database and/or an Internet database. Additionally, in principle, a setpoint storage characteristic variable could also correspond to any other storage characteristic variable, such as for example a setpoint storage condition characteristic variable and, in particular, could be correlated to a storage condition.

The computer unit 26 is intended to determine in an automatic and/or automated manner the storage characteristic variable, in particular as a function of a defined trigger event such as for example closing the household appliance 12. Alternatively or additionally, however, a computer unit could also be intended to determine manually a storage characteristic variable, in particular initiated by a user. For determining a storage characteristic variable of one of the consumer products 16, 17, 18 the computer unit 26 is intended to adjust the consumer product characteristic variable of the corresponding consumer product 16, 17, 18 to the predefined consumer product characteristic variables 22. In particular, in order to minimize incorrect information, in this case the computer unit 26 is intended to consider status information 34 of the corresponding consumer product 16, 17, 18 which is, in particular, stored in the database 20. With a successful adjustment of the consumer product characteristic variable of the corresponding consumer product 16, 17, 18 to the predefined consumer product characteristic variables 22, the computer unit 26 is intended to consider the position and/or location of the corresponding consumer product 16, 17, 18, in particular for the ultimate determination of the storage characteristic variable.

Subsequently, the computer unit 26 is intended to compare the storage characteristic variable with a setpoint storage characteristic variable 36, which is, in particular, stored in the database 20, of the corresponding consumer product 16, 17, 18 and to generate in the present case an, in particular, predefined instruction message 40, 42 when the storage characteristic variable differs from the setpoint storage characteristic variable 36, such as indicated in particular in FIG. 3 by way of example. In the present case, the computer unit 26 is intended to recall at least two different instruction messages 40, 42 from a further, in particular local, database (not shown). Additionally, the computer unit 26 is intended to output instruction messages 40, 42 via the output unit 44. In the present case, the first output element 48 is intended to output the instruction messages 40, 42. Additionally, the second output element 50 is intended to transmit the instruction messages 40, 42 to the electronic device 52, whereby advantageously an instruction function may be implemented.

A first instruction message 40 of the instruction messages 40, 42 in the present case is assigned to the first consumer product 16 which is configured, in particular, as an orange. The first instruction message 40 corresponds in this case to a storage recommendation of the first consumer product 16 outside the household appliance 12. The first instruction message 40 in this case is an image of an object which is correlated to the first consumer product 16 in front of an exemplary background (see FIG. 3).

A second instruction message 42 of the instruction messages 40, 42 in the present case is assigned to the third consumer product 18 which is configured, in particular, as iceberg lettuce. The second instruction message 42 corresponds to a storage recommendation of the third consumer product 18 in a defined partial region of the household appliance 12, in the present case in particular a vegetable compartment. The second instruction message 42 in this case is an image of an object which is correlated to the third consumer product 18 in an illustration of the interior 28 of the household appliance 12.

The second consumer product 17, which is configured in particular as meat, in the present case by way of example is not assigned an instruction message since a storage characteristic variable of the second consumer product 17 coincides with a setpoint storage characteristic variable 36 of the second consumer product 17. Alternatively, it is conceivable to generate just one instruction message and/or a plurality of different instruction messages. Moreover, an instruction message could also be configured alternatively or additionally as a text message. Additionally, a computer unit could also be intended to transmit a minimum shelf life date of a consumer product by means of an output unit and/or to transmit to an electronic appliance by means of a second output element.
